BATTERY
DANGER !
Disconnect the battery cables before contemplating any
kind of soldering work. Arc welding is a carrier of heavy
transients currents and may affect (or destroy) many
sensitive electronic components such as the E.C.U.
Read below recommendations before
operating or servicing the battery. To charge
two independent batteries with a single
alternator, an isolator is available as an
option on most engines. Contact an authorized Nanni
representative.
KEEP CLEAN THE BATTERY
The Battery(ies) should be kept clean and dry. Oxidization
deposits on the battery and on terminals posts may
lead to a wide variety of disturbances like: dead shorts,
voltage drops, premature discharging in wet or cold
weather. In some occurances, these disturbances may
be hard to locate. Use a brass brush to clean battery
terminals posts.
DISCONNECT THE STARTER CABLES
1. Disconnect the negative cable (-) first.
2. Then remove the positive (+) cable.
If the battery is replaced, make sure that the previous
one was the correct model. Check against the table
below:
CONNECT THE CABLES
1. Always connect first the positive lead (+) to the
positive terminal (+) of the battery
2. And then the negative (-).
BATTERY ELECTROLYTE LEVEL
DANGER !
Never touch the battery electrolyte with bare fingers.
The diluted sulphuric acid solution burns skin and will
pierce clothing. Should this occur, immediately wash
garnments with spring water. Obtain medical advice and
assistance without delay for
ELECTROLYTE LEVEL CHECK
As a conservative rule, electrolyte level must always be
above the top of the lead plates (+/-1 cm - slighlty less
than half of an inch). Electrolyte is a mix of sulfuric acid
and water. If level is decreasing, acid concentration is
not supposed to deplete with evaporation. Water alone
must be added, but it is a good practice to check also
the specific gravity with a hydrometer. Follow these
indications :
Unscrew completely the vent plugs and check level with
a flashlight in each and every orifice.
Use a syringe filled with distilled water to top up the
compartment where electrolyte level is too low.
Check gravity in each cell. A reading below 1.215 requires
either charging the battery or to replace it.
If the lead plates are not sulfated and still in good
condition, charging will improve specific gravity.
